Periodic Table of the Elements

The presentation and display of the information in the periodic table is well executed and appealing to the consumer. The Periodic Table complies with section 5.6 of the New Jersey Education Standards for Chemistry which deals with physical science and chemistry. The elements that belong to a group on the periodic table are color keyed. For example, the noble gas group is pink and the Lanthanide and Actinide Series are gray. When an element is highlighted by the cursor, a picture appears to take hold of the attention of the user. While some of the pictures do have meaning, a few appear to be random. Some additional information that can be found on the site is an excerpt about how six new elements were given names. Also, Mendeleev's periodic table is available to inform users on the trends that he recognized. The "Periodic Table Of The Elements" is a superb tool that can be applied to basic chemistry at the high school and undergraduate level. Not only can professors use this when teaching, but students can go back to reinforce concepts. The information provided about the elements is extremely accurate. Access to all of the information in one place reduces the need to travel around the web or go to libraries for answers. In conclusion, the "Periodic Table Of The Elements" is a reliable education tool and well targeted to an audience of science students.

The "Periodic Table Of The Elements" webpage was created as an interactive tool to assist people in navigating the periodic table. The webpage was originally created by Robert Husted while working at the Los Alamos National Laboratory as a Graduate Research Assistant. Following that in 2002/2003, Mollie Boorman revamped the site and added fresh information and graphics to the periodic table. Verification The operating system used while running the applet was Microsoft Windows XP Professional. Using the Internet Explorer and Mozilla Firefox browsers, there were not any bugs or operating issues encountered during testing. On the site, located at http://periodic.lanl.gov/default.htm, menus are easily navigated and links load when they are highlighted. Further practical information that can be found on the webpage is a succinct workshop on the periodic table, definitions to terms that are utilized, and a description of subatomic particles. In addition, an alphabetized catalog of the elements is provided. This resource displays the atomic number and symbol and the elements are interactive. When an element is selected from either the periodic table or the alphabetized catalog of elements, a new screen is displayed with information about the element.

Validation Amongst the selected fields given is atomic number, atomic weight, and electron configuration. Accompanying that is a brief history of the element, sources, properties, and other categories depending on the element selected. The atomic number, symbol, weight and electron configuration of the elements is correct and easily understood. The data given are taken from the CRC Handbook and from the American Chemical Society, and references to sources are given in the body of the page. In addition to all the aforementioned information, the handling of the materials is provided for elements that are commonly analyzed.
